    <p>I'm not sure why this cgi form doesn't work quite right. The problem is somewhere in the main() function but I'm not quite sure how to fix it. The error when run through the interpreter reads:</p> <p>File "ptest.py", line 48, in if (form.has_key("action") and form.has_key("name") \ NameError: name 'form' is not defined</p> <p>Assume proper indention.</p> <pre><code># Import the CGI module import cgi, cgitb # Required header that tells the browser how to render the HTML. print "Content-Type: text/html\n\n" # Define function to generate HTML form. def generate_form(): print "&lt;HTML&gt;\n" print "&lt;HEAD&gt;\n" print "\t&lt;TITLE&gt;Info Form&lt;/TITLE&gt;\n" print "&lt;/HEAD&gt;\n" print "&lt;BODY BGCOLOR = white&gt;\n" print "\t&lt;H3&gt;Please, enter your name and age.&lt;/H3&gt;\n" print "\t&lt;TABLE BORDER = 0&gt;\n" print "\t\t&lt;FORM METHOD = post ACTION = \ \"example_7.1.cgi\"&gt;\n" print "\t\t&lt;TR&gt;&lt;TH&gt;Name:&lt;/TH&gt;&lt;TD&gt;&lt;INPUT type = text \ name = \"name\"&gt;&lt;/TD&gt;&lt;TR&gt;\n" print "\t\t&lt;TR&gt;&lt;TH&gt;Age:&lt;/TH&gt;&lt;TD&gt;&lt;INPUT type = text name = \ \"age\"&gt;&lt;/TD&gt;&lt;/TR&gt;\n" print "\t&lt;/TABLE&gt;\n" print "\t&lt;INPUT TYPE = hidden NAME = \"action\" VALUE = \ \"display\"&gt;\n" print "\t&lt;INPUT TYPE = submit VALUE = \"Enter\"&gt;\n" print "\t&lt;/FORM&gt;\n" print "&lt;/BODY&gt;\n" print "&lt;/HTML&gt;\n" # Define function display data. def display_data(name, age): print "&lt;HTML&gt;\n" print "&lt;HEAD&gt;\n" print "\t&lt;TITLE&gt;Info Form&lt;/TITLE&gt;\n" print "&lt;/HEAD&gt;\n" print "&lt;BODY BGCOLOR = white&gt;\n" print name, ", you are", age, "years old." print "&lt;/BODY&gt;\n" print "&lt;/HTML&gt;\n" # Define main function. def main(): form = cgi.FieldStorage() if (form.has_key("action") and form.has_key("name") \ and form.has_key("age")): if (form["action"].value == "display"): display_data(form["name"].value, form["age"].value) else: generate_form() if __name__ == '__main__': main() </code></pre>

    2. COI cleaned up the formatting a bit. Paste your code and then click the `{}` button to indent everything properly :) Easy peasy. Not sure where the error is coming from. I just tried it on my end and received no errors. Fieldstorage was empty.

    3. COIf we do assume proper indentation, then there is no explantion for the error. You clearly assign it in the same scope as the code using it. It must be indentation problems.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
